BMW has given a glimpse of a new model, which it says is the most technologically advanced it has made.

Packed with innovations, the new 7 Series will make its world debut at the Frankfurt International Motorshow in September and will go on sale in the UK from Spring 2002.

The new 7 Series pioneers a revolutionary ergonomics concept, christened iDrive.

The iDrive idea separates the cabin into two distinct areas, the 'comfort area' and the 'driving area'.

A single central 'controller' now operates most of the secondary functions on the car, including audio, climate control, and navigation.

The result is a dramatic reduction in the number of buttons and switches creating a clean and modern interior look and feel.

The 'controller' is a rotary dial located in front of the central armrest and is intuitive in operation.

By rotating and pressing the 'controller' and moving it laterally, the driver is able to select and control various functions including the ventilation system, the audio and entertainment system, navigation and telematics applications. A central computer monitor displays the various functions and the chosen setting selections.

The new 7 Series also offers Internet access through a WAP-supported BMW internet portal incorporated in the car - a world first, according to the German car maker.

Both the driver and the passenger can operate all the functions in the 'comfort area'.

An instantly noticeable feature of the new 7 Series is the absence of a central gearlever and traditional ignition key.

Instead all primary controls are located in and around the steering wheel, the centre of the 'driving area'. Gear selection for example is controlled via a stalk in the steering column.

A new electronic key controls the ignition switch and the engine is started and stopped using a button. With all the relevant functions positioned in this central 'driving area', the driver can remain focused on the road.

A choice of two V8 engines will be available initially at launch. The 735i will be powered by a 272 horsepower, 3.6-litre while the more powerful 745i will have a 333 horsepower, 4.4-litre engine.

The new 7 Series sets a new benchmark in fuel consumption and performance compared to other cars in its class.

The new 7 Series will feature the world's first six-speed automatic transmission with integrated shift-by-wire technology.

Operated by a selector lever alongside the steering wheel and Steptronic buttons on the steering wheel rim, this innovative transmission also helps to deliver the impressive performance figures. The sprint from standstill to 62mph takes just 6.3 seconds in the 745i and 7.5 seconds in the 735i. Top speed in both models is electronically limited to 155mph.

Safety remains high on BMW's priority list, and the new 7 Series benefits from a number of innovations including improved head airbags, new active head restraints and a new airbag safety control system called ISIS. Via its network of sensors, ISIS decides which safety system to deploy, and when, in the event of an accident. BMW says the system is faster and more precise than the previous sensor system.

Ride quality has also been enhanced making the drive smoother and more comfortable. Continuously variable electronic damper control, pneumatic suspension with automatic self-levelling for the rear axle and a new active all aluminium 'dynamic drive' chassis with active roll stabilisation are all key developments in this area.

Prices, more detailed information and specification of the new 7 Series models will be confirmed closer to launch.
